* scripts/pybootchart: Allow minimum task length to be configured from the ↵Richard Purdie2012-11-202-10/+12
| | | | | | | | | | | | commandline Rather than hardcode the value of "8", allow the minimum task length to be configured from the commandline using the -m option. "-m 0" means all tasks will be graphed. (From OE-Core rev: 30001153d3ce7dadf8f1ec79e634a638a9994518) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* scripts/pybootchart: Fix missing entries bugRichard Purdie2012-11-202-34/+48
| | | | | | | | | | | If two entries have the same start time, the data store used will cause all but one of the entries to be lost. This patch enhances the data storage structure to avoid this problem and allow more than one event to start at the same time.

* pybootchartgui: split the output chart into multiple onesRobert Yang2012-06-152-2/+48
| | | | | | | | | | | | | | | | | | | | Split the output chart into multiple ones to make it more readable, it only works with "-o path", which means that it doesn't work if the user doesn't want to save the chart to the disk. For example: $ ./pybootchartgui.py /path/to/tmp/buildstats/core-image-sato-qemux86/201205301810/ -f svg -s 5 -o /tmp/ bootchart written to /tmp/bootchart_1.svg bootchart written to /tmp/bootchart_2.svg bootchart written to /tmp/bootchart_3.svg bootchart written to /tmp/bootchart_4.svg bootchart written to /tmp/bootchart_5.svg [YOCTO #2403] (From OE-Core rev: 04a34899e1c15a70babd97a3a59ccb9f8af05bad) Signed-off-by: Robert Yang <liezhi.yang@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* pybootchartgui: make the build profiling in picturesRobert Yang2012-06-154-64/+122
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original patch is from Richard, I rebased it to the up-to-date upstream code, here are the original messages from him: We have just merged Beth's initial buildstats logging work. I was sitting wondering how to actually evaluate the numbers as I wanted to know "where are we spending the time?". It occurred to me that I wanted a graph very similar to that generated by bootchart. I looked around and found pyboootchartgui and then hacked it around a bit and coerced it to start producing charts like: http://tim.rpsys.net/bootchart.png which is the initial "pseudo-native" part of the build. This was simple enough to test with. I then tried graphing a poky-image-sato. To get a graph I could actually read, I stripped out any task taking less than 8 seconds and scaled the x axis from 25 units per second to one unit per second. The result was: http://tim.rpsys.net/bootchart2.png (warning this is a 2.7MB png) I also added in a little bit of colour coding for the second chart. Interestingly it looks like there is more yellow than green meaning configure is a bigger drain on the build time not that its unexpected :/. I quite enjoyed playing with this and on a serious note, the gradient of the task graph makes me a little suspicious of whether the overhead of launching tasks in bitbake itself is having some effect on build time. Certainly on the first graph there are some interesting latencies showing up. Anyhow, I think this is the first time bitbake's task execution has been visualised and there are some interesting things we can learn from it. I'm hoping this is a start of a much more detailed understanding of the build process with respect to performance.

* pybootchartgui: add the original codeRobert Yang2012-06-1514-0/+2207
This is from: http://pybootchartgui.googlecode.com/files/pybootchartgui-r124.tar.gz Will modify it to make the build profiling in pictures. Remove the examples since they would not work any more, and they cost much disk space.
